When it comes to air quality, it's essential to make sure that the filtration equipment used is of the highest quality. Medical grade air purifiers are designed to remove 99.7% of airborne particulates, resulting in better air quality and numerous health benefits. These filters are even more effective than HEPA filters, and can remove up to 99.995% of particles of 0.1 micron in diameter from the air. However, electronic air purifiers may produce ozone gas and other pollutants that may be hazardous to health, so filtered air purifiers are considered to be the safest type for home use.
Not all HEPA filters are the same; there are different classes of HEPA filters, according to the standard EN 779. Classic HEPA filters are usually class H10, H11 or H12, and the best HEPA air purifiers will use HEPA H12 filters. HEPA H13 filters are so complete that they are used in medical environments; hence the name “medical grade”. If you're looking for a high-efficiency air purifier, you should look for one with a HEPA H13 filter. The Medify MA-112 is by far the best HEPA H13 air purifier with a medical grade filtration system.
It has a pre-filter designed to capture large particles, such as pet dander, and an activated carbon filter to adsorb odors and other gases such as VOCs (formaldehyde and benzene). The Alen BreatheSmart 45i is another great option; it has 3 types of medical grade HEPA H13 filters, designed to remove dust, mold, and pet odors. It has a noise rate of 51 dB and is energy efficient. Okaysou's AirMax8L also uses HEPA H13 filters in its Ultra-Duo purification system with HepaSilent technology, making it one of the quietest air purifiers on the market.
Finally, Levoit's LV-H135 model comes with a medical HEPA filter that can capture more than 99% of the smallest air pollutants, which are tiny, up to 0.1 microns in size. It has maximum noise levels of 54 dB and is fairly affordable. In conclusion, medical grade HEPA H13 air purifiers are worth it if you want improved air quality and numerous health benefits. They may be more expensive than other types of air purifiers, but they offer superior filtration capabilities that make them worth the investment.
